That's a fan failure, debris should never leave the engine casing due to the forward position - the debris would hammer the fuselage instead of the wing. Turbine point-of-attachment failures are different, for some reason there's an awful lot more rotational energy to contain, and it's easier to design a cowling to mostly contain the damage and for the wing to take a hit. A wing full of kerosene at tens of degrees below freezing is less susceptible to flashfire from hot bits of metal, I think.
The casing can't be said to have failed as it's not designed to *fully* contain a turbine failure as it is a compressor failure.
